Study on zingiber puberulum oil using supercritical fluid extraction (SFE)
Supercritical fluid extraction (SFE) technique was employed to extract the essential oil from the inflorescence of Zingiber puberulum at 48 Mpa and 40°C of extracting pressure and temperature respectively. The oil was then analysed using gas chromatography-mass spectrometry (GC-MS) instrument. Twe...

| Summary: | Supercritical fluid extraction (SFE) technique was employed to extract the essential oil from the inflorescence of
Zingiber puberulum at 48 Mpa and 40°C of extracting pressure and temperature respectively. The oil was then analysed
using gas chromatography-mass spectrometry (GC-MS) instrument. Twenty-one compounds were found in the SFE
extract of Z. puberulum with palmitic acid (65.7%), 1-heptatriacotanol (16.9%) and oleic acid (15.9%) were the major
constituents. Small percentages of various terpenic compounds, i.e. α-bisabolol, β-elemene and caryophyllene were also
identified. It was found that SFE could be used successfully to extract a wide variety of important bioactive compounds
in Z. puberulum but that the conditions may need to be optimized to ensure the optimum yield of the volatile compounds. |
